CONCEALED HINGE Filed April 22, 1938 INVENTOR JOSEPH 5053 BY W ATTOR EYPatented Oct. 24, 1939 UNlTED STATES PATENT OFFIQE Application April 22,

6 Claims.

This invention relates to concealed hinges and particularly to theconstruction of the housing butt part of hinges of this type, and theobject of the invention is to provide a housing butt part formed from asingle sheet metal blank folded to form a U-shaped housing portion withattaching plates extending from one side edge of top and bottom walls ofthe housing at an angle greater than 90 to the web of the housing so asto adapt the housing butt of the hinge to a wide throw hook-shaped butt,and with these and other objects in view the invention consists of adevice of the class and for the purpose specified, which is simple inconstruction, efiicient in use, and which is constructed as hereinafterdescribed and claimed.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawing forms a part, in which the separate parts20 of my improvement are designated by suitable reference characters ineach of the views, and in which:

Fig, 1 is a plan view of a hinge made according to my invention withpart of the construction 5 broken away and also indicating the open andclosed positions of the butts.

Fig. 2 is a view looking in the direction of the arrow 2 of Fig. 1.

Fig. 3 is a side edge view of the hinge as seen in Fig. 1.

Fig. 4 is a view similar to Fig. 1 showing a modification.

Fig. 5 is a section substantially on the line 5-5 of Fig. 4, and 35 Fig.6 is a plan view of a blank from which one of the butts of the hinge isformed.

In Figs. 1 to 3 inclusive I have shown a hinge consisting of ahook armbutt part Ill and a housing butt part I I. The hook arm part in thestructure shown is substantially in the form of a bolt or rod shaped toform the desired hook-shaped arm I2. One straight end of the rod I3 isthreaded to receive nuts or other attaching devices I4, whereas theother end of the arm is enlarged as seen at I5 to form a desired bearingfor the pintle it of the hinge.

The butt part H is formed from a blank l in shown in Fig. 6 of thedrawing. The blank consists of two substantially rectangular plateportions I'I extending into wall portions I8 which form the top andbottom walls of the housing of said butt part which are joined by a webor wall I9. The blank is so shaped and folded as to bring the Web orwall I9 of the housing in the angular position with respect to theattaching 1938, Serial No. 203,520

plates IT, as seen in Fig. 1 of the drawing, as well as to ofiset theweb I9 with respect to one side of the attaching plates. The angularitybetween these Wall portions is greater than 90 as will be apparent. Atthis time it will be understood, however, that this angularity may bevaried to suit different types and kinds of hinges or installation ofhinges.

The wall portions IB also include protruding pintle bearing portions 20which are arranged on the inner side of the web I9 when the butt II isformed, as will be apparent upon a consideration of Fig. l of thedrawing. The portions 20 will be apertured as seen at 2| to receive thepintle I6 of the hinge. At the outer side of the attaching plateportions I! are projecting tongues or flanges 22 which remain in theplane of the plate I'I. These flanges will preferably abut as seen at 23in Fig. 2 of the drawing when the butt part II is completely formed.

It is also preferred that the top and bottom Walls I8 be reinforced byV-shaped corrugations 24 to give greater rigidity and strength to saidwalls and to increase the bearing strength thereof.

In Figs. 4 and 5 is shown a modification in which the butt part I Iadiifers from the butt part I I simply in doming the projecting pintlebearing portion 20a outwardly in the manner clearly seen in Fig. 5 ofthe drawing. The pintle pin or rivet Ilia is disposed centrally of thedomed portions. The parts or elements I'Ia, I8a, I9a and 24a are thesame as the corresponding parts or elements I1, I8, I9 and 24 of thebutt II.

At 25 is shown a hook arm butt part which is substituted for the buttpart II]. The butt part 25 is formed from two similar sheet metal blanksin accordance with the teachings of a companion application Serial No.203,521 filed of equal date herewith, which application has matured intoPatent No. 2,163,713 of June 27, 1939. Each blank is shaped to form anattaching plate portion 26, hook arm portions 21, reinforced as seen at28. The hook arm portions 21 are disposed one directly upon the otherand spot-welded or otherwise secured together as indicated at 29. Theends of the hook arms 2! have outwardly pressed dome portions which seatin the dome bearings 20a. of the butt IIa, as clearly seen in Fig. 5 ofthe drawing. It will also appear that the arms 21 fit snugly within thetop and bottom walls I8a of the butt housing Ila so as to provide astrong bearing for the butt 25 in the several positions thereof withrespect to the butt part II a.

With both forms of construction shown, the outward swinging movement ofthe butts I9, 25

is checked by the engagement of the hook arm with the angular web l9,19a in the manner indicated in dotted lines in Fig. 1 of the drawing. Aspreviously stated, the angularity of this web and its arrangement withrespect to the pintle of the hinge may be varied, within certain limits,to suit various types and .kinds of installations. In like manner theshape and contour of the hook arm of the butts iii, 25 may be varied.Both forms of hinges disclosed to illustrate certain uses of myinvention are of simple and economic construction, and at the same timea strong and durable hinge is provided which may have many uses, butwhich has a practical use in hingedly mounting a vertical door inconnection with the door frame.

In many types of vehicles, such as motor vehicles, airplanes and thelike, the trend of streamlining such vehicles renders it desirable andpractical to use the concealed hinges. To satisfy this use, it is alsodesirable to produce an economical hinge in order that the cost thereofwill :not be prohibitive.

It will also be apparent, however, that a hinge of this type ispractical in the mounting of the dors of large cabinets, closets and thelike, and in fact in connection with doors or closures of any kind orclass where it is desirable and practical to use a hinge of theconcealed type.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is:
